Spied: 2014 Cadillac CTS Sedan is Bigger and Better

Light camouflage gives us the chance to see plenty of new features and get a better idea of overall size.

GM must be getting close to revealing their premium sedan as they shed the heavy cammo while testing the next-gen 2014 Cadillac CTS in Europe. To throw us off the scent, GM engineers applied sticker camouflage to the rear glass to give the sedan a coupe-like appearance. However, we're more interested in what's going on underneath. The CTS Mk3 is in for some big changes, as it moves from the Sigma II platform to a stretched version of GM's RWD 'Alpha' platform underpinning the ATS.

This should help it compete directly with the BMW 5-Series, Audi A6, Lexus GS and Mercedes E-Class models. From the spy shots we can see the new CTS has grown in length and possibly in width too while the angular look of Cadillac's Art and Science design theme has also been applied. In addition to getting a pretty good peek at the grille, which sports a V-patterned design, other visible features include LED daytime running lights, a large pair of rectangular chrome exhaust tips, front & rear radar senses, and Brembo brakes.

While we were initially hopeful this might be a CTS-V prototype, the rear brakes look too small and there are no distinctive V-series design cues. For the entry-level model, the 2014 CTS should inherit the 270hp, 2.0L turbocharged four-cylinder from the ATS, marking the first time the CTS has featured four-cylinder power. The upmarket CTS will likely continue to feature a 3.6L V6, while the next-gen CTS-V is rumored to be inheriting a version of the C7 Corvette's V8. Watch for production of the new CTS to start at the Lansing Grand River Assembly plant in September 2013.
